Renault Car - Defective Vehicle

I bought kwid climber AMT on *th may **** from NGM Automobiles Moradabad.
This car need servicing on **th may ****, which was **th day of this practically brand new vehicle.
Issues were: (FIRST RECALL)(DAY **)
*- Display showing engine fault.
*- With full accelerator speed could’t be increased to more than ** kmph
Workshop employees took this car to workshop and said:
*- There had been an RPM problem, which they now corrected.
*- They also updated the car software.
They returned the car on same day
Again the issues arose while driving
Issues were:
*- Meter AGAIN showing engine fault
*- Speed could not be controlled by accelerator
*- Intermittently, with full accelerator, speed could’t be increased to more than **kmph
*- AND, intermittently, without pressing accelerator, speed increased up to maximum speed
Workshop employees again took this car to workshop on **th June **** and said:
RECALL * –DAY-**
*- They have changed the accelerator pedal
*- They have changed the wiring of the car
This time they returned the car on **th June **** – that is, AFTER ** days.
AFTER ALL WAS CHANGED IN THIS NEW CAR, STILL,
RECALL – *- DAY **
The Passenger seat Seat belt alarm went off, without anyone being in the seat (this time, I did not take a video because every time anyway something or the other was going wrong with the car)
I asked a professional driver to just drive the car and see, to confirm what I was finding wrong in the car.
The car speed did not match with the accelerator
Pick up was slow
Car overall performance was poor
After joint drive with the driver, the Dealer workshop again said there is nothing wrong with the car, BUT THEY WANTED TO TAKE THE CAR TO THE WORKSHOP AGAIN!
I am frustrated with the car. I have driven other cars and I know a poor performing car when I see/ drive one. Still I was ready to give it a chance when they asked to relook at the car once. But EVERYTIME, AN ISSUE IS COMING UP AND THEIR RELOOKS are just not GETTING OVER. Hence, completely disheartened, and having wasted so much time and visits to the showroom/local workshop and back, I asked them to take this car back as this car is not safe to drive further but the COMPANY WANTS TO TAKE THIS CAR TO WORKSHOP AGAIN!!!!!
